OIL-BURNER.-

SPECIFICATION forming part of Letters Patent No. 717,937, dated January6, 1903. Application filed May 5,1902. Serial No. 105,873. (No model.)

To aZZ whom, it may concern:

Be it known that I, GUY W. SMITH, a citizen of the United States,residing at San Jose, in the county of Santa Clara and State ofCalifornia, have invented certain new and useful Improvements inOil-Burners, of which the following is a specification.

My invention relates to improvements in oil-burners, the object of myinvention being to provide an oil-burner which will deliver the vaporgenerated from the oil in a perfectly dry and highly-heated condition.For this purpose-it is the object of my invention so to construct theburner that the flamesof the gas generated therein shall be deflectedagainst the retort for vaporizing the oil and shall be utilized in themost eflective manner for highly heating said retort, thus generating avery dry oil-vapor and producing a perfectly smokeless flame.

A further object of the invention is to ac.- complish the above resultin a very cheapand simple manner, so that the burner can be sold at alow price and require little care or atten tion to keep in order.

My invention also resides in the novel con: struction, combination, andarrangement of parts for the above ends hereinafter fully specified, andparticularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side view of my improvedburner. is a vertical section thereof. Fig. 3 is a plan view of theretort, the lid being removed. Fig. 4 is a bottom plan view of the lid.Fig. 5 is a perspective view of the spreader removed.

Referring to the drawings, 1 represents the retort of the burner, and 2the lid therefor. Said retort is provided at its upper end with anoutwardly-extending flange 3, in which is formed a channel or conduit 4for the oil. Said channel or conduit is covered with an annular sheet ofasbestos 6, which is perforated, as shown at 7, to permitthe oil to passthrough into the channel. The oil enters the burner by means of a pipe 8screwed into a passage 9 formed in the lid and extending downward anddischarging through said aperture 7 in the asbestos sheet, whichaperture registers with said passage 9. The oil flows through saidaperture into said conduit, which Fig. 2.

extendscircularly for almost a complete cir cle and then turns uponitself as shown at 10, and extends in an inner circular path to a point11 opposite the aperture 7, when it turns inward from said pathinto theretort.- chamber 12, formed in the main portion or retort. From saidretort-chamber the vapor now formed flows outward through pipes 13,closed by caps 14:, and discharges upwardly through apertures 15. Thevapor being ignited at said apertures, the flame of the burningvaporimpinges against wings or spreader-plates 16, formed on the end ofa spreader 17, which is laid on the top of the burner, so that saidspreader-plates are vertically above said apertures. By means of saidspreader-plates the flames are deflected downward and highly heat theretort and the flange, thus vaporizing the oil flowing along theconduit.

An important feature ofmy invention resides in the means for bringingthe retort to and maintaining it at a high heat. It is very importantthat the retort should be maintained at a very high temperature in orderto insure that the gas delivered therefrom shall be thoroughly vaporizedand highly heated, thus giving the best result in its combustion. Thisis insured by means of the annular flange 3 in combination with thewings 16 of the spreader extending down below the level of said flange.With this construction the effect is produced that the flames impingingagainst the under sides of the spreader-wings and deflected therefromare directed against the retort on the under side of the flange 3. Theflange and retort are thus very highly heated. Without said flange theretort could not be so thoroughly heated by means of the spreader, asthe flames would tend to pass upward around the sides of theretortwithout being brought into close contact with the same. In my inventionthe flames are positively forced against the under side of the flangeand also against the sides of the retort, and thus the retort is highlyheated, thereby completely vaporizing the gas therein and delivering itat a very high temperature.

The cover and retort are provided with registering peripheral lugs 18,which are connected together by short bolts 19, passing upwardly throughthe registering lugs and hav ing nuts 20 screwed upon the upper endthereof.

1 have found that with this construction of burner I am enabled to usethe very lowest grade of oil or distillate, costing about four cents agallon. I have also operated such a burner continuously for three monthsin a domestic stove for cooking and heating without its needing anyrepair, cleaning, or to be taken apart forany purpose whatever;

I claim 1. An oil-burner comprising a retort having an annular flange orprojection extending laterally from the body thereof, conduits for thegenerated gas extending laterally from the lower portion of the retort,and having upwardly-directed apertures, and a spreader supported uponsaid retort and having Wings arranged above the apertures and at such aheight with reference to said flange as to deflect the flames from theapertures against the under side of said flange to heat the retort,substantially as described.

2. In an oil-burner, the combination of a retort having a flange orprojection extending laterally from the body thereof, conduits for thegenerated gas extending laterally from the lower portion of said retort,and a spreader comprising a cross-piece laid upon the top of the retortand having downwardlyextending arms and wings carried by said arms abovethe apertures in the conduits and at a height to deflect the flamesimpinging thereon against the under side of the flame, substantially asdescribed.

In witness whereof I'have hereunto set my hand in the presence of twosubscribing witnesses.
